PVD vacuum coating machine evaporation coating is the most common coating method. Many conventional daily necessities around us are coated through resistance evaporation. Compared to other coating methods, resistance evaporation coating has low film quality requirements, low cost, and product materials and characteristics should also comply with the principle of evaporation coating. Below, we will summarize the vacuum editor to explain the working mode of the PVD vacuum coating machine evaporation system, I hope it can help everyone:

The evaporation system of PVD vacuum coating equipment mainly refers to the film-forming device. There are many film-forming devices in PVD coating machines, and there are various methods for PVD coating, such as resistance heating, radio frequency sputtering, ion plating, etc. The following introduces the methods of PVD coating resistance heating and electron gun evaporation:

PVD coating resistance evaporation is currently the most widely used evaporation method based on its structure and working principle, and PVD coating is also the longest applied evaporation method. The working method of PVD coating is that the tungsten sheet is made into a boat shape by PVD coating, which is installed between two electrodes, and then heat is transmitted to the PVD coating material. When the heat of the tungsten boat is higher than the melting point of the PVD coating material, the material sublimates or evaporates. PVD coating is easy to operate, simple in structure, and low in cost.

PVD coating electron gun evaporation is the most widely used evaporation method so far. PVD vacuum coating machine can evaporate any type of PVD coating material. The working method of PVD coating is to place the coating material in a crucible, and PVD coating will make the evaporation source into a filament shape. PVD coating, due to the material of the filament being tungsten, forms an electron beam. PVD coating, due to the high temperature of the electron beam, PVD coating can melt any coated medicinal herbs and coagulate them.
